Periodic structure on a Fe(30nm)/Al(120nm) thin metallic film on glass substrate produced by
Laser Interference Metallurgy. The sample was irradiated with an interference pattern produced
with three laser beams. Because planar laser waves are applied, this structuring can proceed
for the macroscopic diameters of the laser beam and consequently it allows a fast functionalization
of surfaces with dimensions of technical relevance. 20µm scan. Imaged with the MFP-3D AFM.
